Background: Positive resection margins after conization or loop electrosurgical excision procedure (conization/LEEP) are associated with increased risks of recurrence or residual cervical intraepithelial neoplasia (CIN). Herein, we investigated the long-term outcomes of photodynamic therapy (PDT) for incomplete excision of CIN3.

Methods: We retrospectively reviewed the medical charts of 73 patients treated with PDT between 2000 and 2011.

Improved cytoreductive surgery for advanced stage ovarian cancer (OC) represents a critical challenge in the treatment of the disease. Optimal debulking reaching no evidence of macroscopic disease is the primary surgical end point with a demonstrated survival advantage. Targeted molecule-based fluorescence imaging offers complete tumor resection down to the microscopic scale.

Analysis of cancer-derived extracellular vesicles (EVs) in biofluids potentially provides a source of disease biomarkers. At present there is no procedure to systematically identify which antigens should be targeted to differentiate cancer-derived from normal host cell-derived EVs. Here, we propose a computational framework that integrates information about membrane proteins in tumors and normal tissues from databases: UniProt, The Cancer Genome Atlas, the Genotype-Tissue Expression Project, and the Human Protein Atlas.

Intraperitoneal (IP) chemotherapy for ovarian cancer treatment prolongs overall survival by 16 months compared to intravenous chemotherapy but is not widely practiced due to catheter-related complications and complexity of administration. An implantable, nonresorbable IP microdevice was used to release chemotherapeutic agent at a constant rate of approximately 1.3 μg/h in vitro and 1.

Highly sensitive detection of small, deep tumors for early diagnosis and surgical interventions remains a challenge for conventional imaging modalities. Second-window near-infrared light (NIR2, 950-1,400 nm) is promising for in vivo fluorescence imaging due to deep tissue penetration and low tissue autofluorescence. With their intrinsic fluorescence in the NIR2 regime and lack of photobleaching, single-walled carbon nanotubes (SWNTs) are potentially attractive contrast agents to detect tumors.

In omics studies aimed at the early detection and diagnosis of cancer, bioinformatics tools play a significant role when analyzing high dimensional, complex datasets, as well as when identifying a small set of biomarkers. However, in many cases, there are ambiguities in the robustness and the consistency of the discovered biomarker sets, since the feature selection methods often lead to irreproducible results. To address this, both the stability and the classification power of several chemometrics-based feature selection algorithms were evaluated using the Monte Carlo sampling technique, aiming at finding the most suitable feature selection methods for early cancer detection and biomarker discovery.

Objectives: Despite improved knowledge regarding the etiology of ovarian cancer, as well as application of aggressive surgery and chemotherapy, there has been only a modest change in the mortality statistics over the last 30 years. Given these results and the evolution of targeted therapies, there is an increasing need for prognostic and predictive factors to stratify patients for individualized care. Many laboratories have also investigated the specific individual biomarkers correlating them with clinicopathologic characteristics.

Uterine leiomyomas (fibroids), the most common benign tumor in women of childbearing age, can cause symptoms including dysmenorrhea, menorrhagia, urinary symptoms, pain and infertility. Hysterectomy is a common approach to treating uterine fibroids, and less invasive surgical approaches such as myomectomy and uterine artery embolization also have been shown to alleviate symptoms. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is the only totally non-invasive surgical approved method for treating uterine fibroids.

Objective: To test the efficacy of a new scoring system to differentiate high-risk hydatidiform mole (H-mole) and initiate early selective postmolar chemotherapy.

Study Design: According to Kim's scoring system, 262 patients were identified as high-risk H-mole patients. Fifty (19.

Objective: To evaluate the changing epidemiologic picture and clinical characteristics of gestational trophoblastic disease (GTD) in South Korea over the past 5 decades.

Study Design: Patient data were collected from 37 hospitals nationwide, the Korean Research Institute of Trophoblastic Disease registry and CHA University Comprehensive Gynecologic Cancer Center from the years of 1970s through the year 2002. Demographic data, pretreatment evaluation, treatment modality, chemotherapeutic regimen and their results according to the clinical International Federation of Gynecology and Obstetrics classification and World Health Organization prognostic score were analyzed.
